One can then consider the \(\Delta \rightarrow 0\)  limit and set \(C = 0\)  and \(n=1\)  to recover the dispersion in [1]}. \(\gamma = \pm \)  indicates the node d.o.f as can be seen by its effect on \(b_0\)  and \(C\) , and \(s=\pm \)  represents the valley d.o.f. In the case \(N < n\) , we have the \(n\)  degenerate chiral ground states which are characterized by the dispersions:
\(E_0^{\gamma } &= \gamma \sqrt{\left[(v-C) k_z - b_0\right]^2 + \Delta ^2}.\)
